FIREARM.

Application filed September 11, 1924, Serial No. 737,035. RenewedNovember 19, 1927.

This invention relates to firearms and is particularly adapted for useon firearms of the type shown in the Patents 719,955, Feb. 3, 1903, and789,755 May 16, 1905, to John D. Pedersen. These patents disclose afirearm of the magazine type, particularly adapted to accommodate shotshells. Such shells or cartridges are loaded into a tubular magazinefrom the rear end thereof, and are retained therein by a stop or lugconsisting of a stiff spring attached to the carrier. As the forearm andaction bar are retracted in the operation of loading the gun, thecarrier is rotated to release the rearmostcartridge from the stop, saidcartridge then slides rearwardlyonto a suitably constructed part of thecarrier. On the forward move ment of the action bar the carrier isusually rotated to elevate the cartridge into alignment with thechamber, and the stop lug is thereby brought into position to engage thebase of the next cartridge. The lifted cartridge is pushed into thechamber by the The firing pin and cooking ment of the action bar, and asthe action bar and breech block reach their final forward positions theaction bar is locked against another rearward movement until the hammerhas moved forward to fire the shell in the chamber.

'In this gun as hitherto constructed, in order'to remove shells from themagazine without firing them, it has been necessary to release theaction bar lock by means provided for this purpose, and to repeatedlyoperate the action bar, each shell in turn passing through the sameseries of movements as though it had been fired, or by carefulmanipulation each shell may be removed from the position in which it iselevated into line with the chamber but has not yet entered the chamber.This necessity arose from thefact that shells were retained in themagazine by a latch of such construc: tion that it could not be readilydisplaced.

Even the operation of loading the magazine was difficult owing to thenecessity for forcibly-displacing this semirigid latch memher.

One object of this invention is to provide an improved means forretaining shells or cartridges in the magazine,

A further object of this invention is to provide means whereby shells orcartridges may be removed directly from the magazine without operatingthe action bar.

A further object of the invention is to provide an improved cartridge orshell stop which can be manually moved to ineffective position, therebypermitting the removal of the shells in the magazine.

With these and other objects in view my invention consists in the novelcombinations and arrangement of parts hereinafter described andillustrated in the drawings.

In said drawings Fig. 1 is a vertical longitudinal section through thereceiver of a firearm embodying my invention.

Fig. 2 is a horizontal section on the line 22 of Fig. 1.

Fig. 3 is a perspective of my improved shell carrier and stop showingthis member in engagement with the head of a shell.

he receiver 10 which encloses the main parts of the operating mechanism,has an opening 11 at the bottom to permit of loading and ejecting theshells. The breech block 12 when at the limit ofits forward movementengages a recoil shoulder 13 on the receiver frame, locking the breechblock against rearward movementuntil released from said shoulder. Thebreech block is recessed to receive a firing pin 14, inserted thereinfrom the rear, and terminating at its rear end in a cocking head 15comprising a shoulder 16 adapted to be engaged by a sear 17, which isheld in engagemei'it with shoulder 16 byj a sear spring 18. The scarcomprises a laterally extending foot 19 which extends under the forwardend of the trigger 20.

The breech block is adapted to be reciprocated thru its connection witha forearm 21, which encircles a magazine 22 adapted to receive a columnof cartridges. The forward cartridge in said column engages the plungerwhich is pressed rearwardly by spring 24. The means for retaining shellsin the magazine and for transferring them one at a time from themagazine to position to be pushed into the chamber by the breech block,will now be described.

carrier comprising a spindle 25 having a wing or blade 26 rigidtherewith, lies in a longitudinal recess in the Wall ofthe receiver 10,and is journalled in the ends of said recess for rotation about alongitudinal axis. Integral with the spindle 25 near its rear end is aspiral cam follower 261, adapted to engage a cam groove in the breechblock. Fixed to, the carrier is a guide lug 27 which forms a lowersupport and guide for the b e l k ur ng: th major par of its movement.Pivoted on. the carrier near its forward end is a shell stop or latch28, adapted when said carrier is in normal position, to retain theShells in the magazine by engaging the head of the rearmost temperarilyretain the shells when the car, rieris rotated so that latch28 isineffectivefor this purpose, aswill be presently explained; Theoperation of the carrier is, as follows: r f

WVhen the breech block is forward the carrier blade 26' standsvertically at one side o f'th'e beech block, in a recejss'in thereceiver wall. As the breech block moves rea'rwardly. the carrierremains in this position'ywhile the shell in the chamber is extractedand ejected downward past] the carrier'by the spring pressed ejector 31.After this has occurred, and very near the end of the rearward; movementof the breech block I the carrier is rotated-by the engagement of spiralcam 261 with asuitably shaped part of the cam groove262 on the breechblock.

h m me Places he arr er blade S stantially transversely'ofthe receiver,in

which position it isa dapt ed to receive the I shellto'b'e released fromthe magazine. Near the end of the carrier movementthe pivoted stop orlatch 28 moves laterally off the head of the reai'most shell, whichshell under the pressure of the magazine spring-29 moves back'onto thecarrier, the next cartridge in front'being stopped bytem'porary catch30. As the breech block begins to move forward the.ca rrier isreversely. rotated, lifting the shellthereon into alignment with theher. The carrier does not return atonce to its normal inactive posltlon.lnfthe recess in the receiver wall, but remains in a position in whichit supports-theshell between the, breech block and, the chamber whilethev breech blockadvances and begins, to slide, the

shell into the chamber, the icontrolling.cam groove 262011. the; breechblock being, snitably shaped for this purpose. At thelprop'er time thecarrier returns to. inactive position, the rearmost shell in themagazine resting against the latch '28, tijo-n is complete. V

My invention renders it possible to unload the magazine withoutoperating the action bar at all. The shells in the magazine are retainedsolely by latch v 28, which latch is held in effective position by acomparatively light spring 29. Latch 28 can, therefore, be manuallyretracted at will to releasethe. rears m st Sh l, which Shell: is thenremoved, and the operation repeated for each shell in the magazine. Thepivotal mounting of this latch also permits its ready deflection 1nloading the magazine.
